Here's a picture of a friend's 7K trailer after he loaded up with firewood at my place. His tow vehicle is a 2008 Toyota Sequoia rated for a bit over a 10K trailer. A few months later I asked him "what brake controller do you have in your Sequoia?" His response "oh, the factory brake controller....just push "tow/haul" and you're good." He was a little surprised when I told him Toyota doesn't offer a brake controller for the Sequoia or Tundra yet (I have a 2007 Tundra) and the tow/haul button just changes the transmission shift points. So, no brakes on the trailer prior to a 50mi drive home...wonder what it weighed (pretty wet Ash mostly)?
